In CORROSION’S June 2020 editorial,1 we explored the COVID-192 pandemic and the antimicrobial function of copper and silver enabled by corrosion Since that editorial was written, we have gone from 2 1 million confirmed infections and over 143,000 r

Because of the high cost of energy, hydrometallurgy is frequently preferred to smelting to extract metals from ores. Many of these processes involve leaching of the metal with an acid, often sulfuric acid. However, there are some processes that use a

Iron (Fe)- and manganese (Mn)-oxidizing bacteria are often cited individually and collectively as putative microorganisms for microbiologically influenced corrosion (MIC). The two groups of microorganisms have in common the ability to attach to surfa

The native surface oxide upon a single phase low-density compositionally complex alloy (CCA), AlTiVCr, was studied herein—owing to its exceptionally high aqueous corrosion resistance. The nature of the native surface oxide/surface film was elaborat

The presence of absorbed hydrogen (H) within pure iron and most steels (including carbon and stainless steels) has been found to increase their corrosion. Historically, the enhanced corrosion of H-charged steels has been attributed to the ability of

A model has been developed for predicting the localized corrosion repassivation potential (Erp) for alloys in environments containing chloride ions and hydrogen sulfide. The model has been combined with Erp measurements for a 13-Cr supermartensitic s

In the present study, two composites, reinforced with 25 vol% SiC particles with average sizes of 3 μm (micrometer-sized, composite A) and 0.7 μm (submicrometer-sized, composite B), respectively, were evaluated to investigate the effect of reinforc
